| [#16] 我都有一個難提，關於噴嘴 https://en.wikipedia.org/wiki/PET_bottle_recycling 而家裝消毒酒精D膠樽(去到＞95%) "多數" 都係用PET, PE & PP。 Bottles made of polyethylene terephthalate (PET, sometimes PETE) can be used to make lower grade products, such as carpets.[citation needed] To make a food grade plastic, the bottles need to be hydrolysed down to monomers, which are purified and then re-polymerised to make new PET. In many countries, PET plastics are coded with the resin identification code number "1" inside the universal recycling symbol, usually located on the bottom of the container. PET is used as a raw material for making packaging materials such as bottles and containers for packaging a wide range of food products and other consumer goods. Examples include soft drinks, alcoholic beverages, detergents, cosmetics, pharmaceutical products and edible oils. PET is one of the most common consumer plastics used.[1] Polyethylene terephthalate can also be used as the main material in making water-resistant paper. 最後修改時間: 2019-03-11 19:08:48 |

| [#17] 我都有一個難提，關於噴嘴 #16 多謝資料。 但我都係吾會用黎裝香水，膠始終有味，混埋香水就真好味。 消毒酒精無所為，因為作用吾同香水。 多年前有人話 PET 1 膠樽吾好洗完再裝水飲。我無跟進，新既PET 1 物料可能好的。 |

Any suggestions? I have a problem with dissolving of Bis-Phenol A (BPA) in water. Are there any suggestions? I need to prepare BPA aqueous solutions e.g. 30 ppm. TNX 5 years ago Henrik Rasmus Andersen Technical University of Denmark Be careful with carbonate and bicarbonate together with AOP treatment. Both ions scavenge hydroxy radicals so the AOP becomes less effective. Methanol and ethanol also disturbe AOP. I suggest ultrasonification or increase pH with strong base, as soon BPA is dissolved adjust back to neutral with strong acid. 5 years ago Henrik Rasmus Andersen Technical University of Denmark Be careful with carbonate and bicarbonate together with AOP treatment. Both ions scavenge hydroxy radicals so the AOP becomes less effective. Methanol and ethanol also disturbe AOP. I suggest ultrasonification or increase pH with strong base, as soon BPA is dissolved adjust back to neutral with strong acid. 5 years ago Henrik Rasmus Andersen Technical University of Denmark The solubility of bisphenol A is higher than 30 mg/L so you properly just experience slow dissolution. Ultrasonication can help. If you need to dissolve higher concentrations than the "regular" solubility of about 100 mg/L it helps to bring the pH up to around 10. 5 years ago Imre Tóth University of Pannonia, Veszprém The addition of a few percent of MeOH could probably help, especially when added to a suspension of 100-200 ppm Bisphenol A in water. If MeOH disturbs you should obviously remove it by some means (distillation?). By the literature at least about 120 ppm bisphenol A should dissolve at 25 C. You can try to heat up a saturated solution and filtering it after cooling back. You could also try ultrasonic mixers or mildly alkaline solutions (in case a little salt content is not disturbing, for example adding an equiv. amount of bicarbonate to a 100-200 ppm solution and neutralizing it back to pH 4-5.) https://www.quora.com/Is-alcohol-acidic-or-basic Is alcohol acidic or basic? Steven Fawl, Professor of Chemistry at Napa Valley College (1985-present) Answered Feb 19, 2018 · Author has 397 answers and 467.5k answer views Originally Answered: How is alcohol acidic? Let me be very clear about this answer. Despite all claims to the contrary, alcohol is acidic. I have been teaching organic chemistry for more than 30 years and the one idea that I demand that all of my students know is that alcohols behave as acids. Organic chemists divide solvents into two categories, protic and aprotic. A protic solvent is one that is capable of donating an H+ ion to the solution. Alcohols fall into this category. When not being used as solvents, alcohols are frequently used as nucleophiles. A common reaction that is done in an organic chemistry lab is called the Williamson Ether Synthesis. |
